6. ADJUSTMENT

6.1  CD ADJUSTMENT

1) Cautions on adjustments
• In this product the single voltage (3.3 V) is used for the 
regulator.  The reference voltage is the REFO1 (1.65 V) 
instead of the GND.
If you should mistakenly short the REFO1 with the GND 
during adjustment, accurate voltage will not be obtained, 
and the servo’s misoperation will apply excessive shock 
to the pickup.  To avoid such problems:
a. Do not mix up the REFO1 with the GND when 
connecting the (-) probe of measuring instruments. 
Especially on an oscilloscope, avoid connecting the (-) 
probe for CH1 to the GND. 
b. In many cases, measuring instruments have the same 
potential as that for the (-) probe.  Be sure to set the 
measuring instruments to the floating state.
c. If you have mistakenly connected the REFO1 to the GND, 
turn off the regulator or the power immediately.

• Before mounting and removing filters or leads for 
adjustment, be sure to turn off the regulator.

• For stable circuit operation, keep the mechanism 
operating for about one minute or more after the 
regulator is turned on.

• In the test mode, any software protections will not 
work.  Avoid applying any mechanical or electrical 
shock to the mechanism during adjustment.

• The RFI and RFO signals with a wide frequency range 
are easy to oscillate.  When observing the signals, 
insert a resistor of 1 k ohms in series.

• The load and eject operation is not guarantied with the 
mechanism upside down.  If the mechanism is blocked 
due to mistaken eject operation, reset the product or 
turn off and on the ACC to restore it. 

2) Test mode
This mode is used to adjust the CD mechanism module.
• To enter the test mode.
While pressing the LIST and TA/NEWS keys at the 
same time, reset.
• To exit from the test mode.
Turn off the ACC or back up.

Notes:
a. During ejection, do not press any other keys than the 
EJECT key until the loaded disc is ejected.
b. If you have pressed the (

) key or (

) key during focus 

search, turn off the power immediately to protect the 
actuator from damage caused by the lens stuck.
c. For the TR jump modes except 100TR, the track jump 
operation will continue even if the key is released.
d. For the CRG move and 100TR jump modes, the tracking 
loop will be closed at the same time when the key is 
released.
e. When the power is turned off and on, the jump mode 
is reset to the single TR (91), the RF amp gain is set to 0 dB, 
and the auto-adjustment values are reset to the default 
settings.
